I have been making EPS foam decoys using a Decoys Unlimited mold for the past few years. I use a propane cooker to boil the decoys, but this doesn't work well in Michigan in the winter. Does anyone have any advise on an indoor cooker that is not too expensive to buy or build (around $100.00). I would really like to be able to make decoys over the winter when I have a little more time.
